1 Installation precautions
Installing the switch
•
The switch is heavy. For rack stability, install it at a lowest possible position on the rack.
•
Hold the chassis handles to move the switch. Do not hold the handle of a fan tray, a power
module, or a module, or the air vents of the chassis to move the switch. Any attempt to move the
switch with these parts might cause equipment damage and even bodily injury.
•
The switch is heavy. As a best practice, use a mechanical lift, such as forklift truck, to move and
carry the switch to the rack. If no mechanical lift is used, cooperate with a minimum of four
people to move the chassis by using the chassis handles.
•
Remove the fan trays, power modules, and filler panels from the switch before moving it.
Reinstall these components after installing the switch in the rack.
•
Do not place your hand into any slot when you move the chassis.
•
Place the switch on the slide rails from the front of the rack to prevent the mounting brackets
from hindering the rack-mounting of the switch.
•
After placing the switch on the slide rails, do not leave go of your hands immediately because
this might tip the switch, damaging the switch or even causing bodily injury
•
Reliably grounding the switch is crucial to lightning protection and EMI protection. Ground the
switch reliably before you use it.
Installing a module
•
When you install a module, avoid touching the connectors on it.
•
If you are not to install a module in a module slot, install a filler panel in the slot.
•
A fan tray covers fabric module slots. Install fabric modules or filler panels in the fabric module
slots before installing a fan tray.
•
To replace or install a fabric module for an operating switch, first remove the fan tray that covers
the slot of the fabric module. Install the fan tray immediately after the replacement or installation.
After the fan tray starts operating, you can replace or install fabric modules whose slots are
covered by the other fan tray.
•
When you hot swap a fabric module, only one fan tray is operating and it automatically
increases the fan speed. Take noise protection measures such as wearing an earmuff or
earplug. In addition, make good preparation before hot swapping a fabric module to minimize
the operation time.
•
To prevent a filler panel from being drawn into the chassis when fan speed is high, use both
hands to grasp the filler panel by its two sides during filler panel installation and removal on an
operating switch.
Installing a fan tray
•
When installing and removing the fan tray, keep your hands and fingers away from the spinning
fan blades.
•
To avoid fan tray damage, use both hands when installing or removing a fan tray.
•
A fan tray covers fabric module slots. Install fabric modules or filler panels in the fabric module
slots before installing a fan tray.

1-2
•
The switch provides two fan tray slots. To ensure normal operation of the switch and reduce
noises, install a fan tray in each slot.
•
To prevent dust from entering the chassis, make sure each fan tray slot has a filler panel or fan
tray installed when the switch is not in use.
•
The fan tray is hot swappable. When you hot swap a fan tray, ensure electricity safety. You can
hot swap a fan tray only when the other fan tray is operating correctly.
•
When you hot swap a fan tray, the fan speed of the remaining fan trays automatically increases.
Take noise protection measures such as wearing an earmuff or earplug. In addition, make
preparations before hot swapping a fan tray to minimize the operation time.
Connecting the power cords
•
Power on the switch after you have installed fan trays on the switch.
•
Make sure each power cord has a separate circuit breaker at the power input end.
•
Turn off the circuit breaker before you connect a power cord.

modules might emit invisible laser light. Do not stare into
beams or view directly with optical instruments when the switch is operating.
Examining the installation site
The switch must be used indoors. To ensure correct operation and long service life of your switch,
make sure the installation site meets the following requirements.
Weight support
Make sure the floor or ground at the installation site can support the combined weight of the switch
and the rack. The total weight of the switch includes the chassis and its components (for example,
modules and power modules) and accessories. For the weights of the switch and its components,
see "Chassis view and technical specifications" in H3C S12500G-AF Switch Series Hardware
Information and Specifications.
To mount the switch in a rack, select slide rails that can support the total weight of the switch.
To assess the load-bearing requirements for the floor and slide rails, take potential system expansion
(for example, adding more modules) also in consideration.
Temperature
CAUTION:
If condensation appears on the chassis when you move it to a high
-temperature environment, dry
the chassis before powering it on to avoid short circuits.
If the temperature in the equipment room is too high, too low, or changes dramatically, the device
reliability is reduced and its service lifetime is shortened. For long-term, highly available operation of
the device, make sure temperature and humidity in the equipment room meets the requirements
described in Table2-1.

2-3
Table2-1 Temperature requirements
Temperature Range
Operating temperature 0°C to 40°C (32°F to 104°F)
Storage temperature –40°C to +70°C (–40°F to +158°F)
Humidity
Maintain appropriate humidity in your equipment room, as described in Table2-2.
•
Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
•
Lasting low relative humidity can cause washer contraction and ESD and cause problems
including loose mounting screws and circuit failure.
Table2-2 Humidity requirements
Humidity Range
Operating humidity 5% to 95%, noncondensing
Storage humidity 5% to 95%, noncondensing
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points. In the worst case, electrostatic adsorption can cause
communication failure.
Table2-1 Dust concentration limits in the equipment room
Substance Particle diameter Concentration limit
Dust particles ≥ 0.5 µm ≤ 3.5 × 106particles/m3
Dust particles ≥ 5 µm ≤ 3 × 104particles/m3
Dust (suspension) ≤75 µm ≤0.2 mg/m3
Dust (sedimentation) 75 µm to 150 µm ≤1.5 mg/(m2h)
Corrosive gases can accelerate corrosion and aging of components. Make sure the corrosive gases
in the equipment room do not exceed the concentration limits as shown in Table2-2.
Table2-2 Corrosive gas concentration limits in the equipment room
Gas Average concentration (mg/m3) Maximum concentration (mg/m3)

NH31.0 3.0

2-4
Gas Average concentration (mg/m3) Maximum concentration (mg/m3)
O30.05 0.1
NOX0.5 1.0
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
•
A conduction pattern of capacitance coupling.
•
Inductance coupling.
•
Electromagnetic wave radiation.
•
Common impedance (including the grounding system) coupling.
To prevent EMI, perform the following tasks:
•
If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
•
Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Grounding
Correctly grounding the switch is crucial to lightning protection, anti-interference, and ESD
prevention. Use a good grounding system for the switch. Make sure the resistance between the
chassis and the ground is less than 1 ohm.
For more information about grounding the switch, see "Grounding the switch."
Power
Perform the following tasks to meet the power requirements:
1. Calculate the system power consumption.
The system power consumption varies by module types and quantities. For more information
about the system power consumption, see "Chassis views and technical specifications" in H3C
S12500G-AF Switch Series Hardware Information and Specifications.
2. Identify the number of power modules based on the system power consumption.
